Astronomers have documented how the radiation wind from nearby star giants erodes the protoplanetary disk of a young star. This means that the building material for gas planets is lost… more

Why are there so surprisingly few exoplanets twice the size of Earth? Astronomers have now provided a possible explanation for this gap in the size distribution… more

Astronomers have succeeded in detecting the spectral signature of water vapor in the gas envelope of a nearby, potentially water-rich exoplanet… more

Astronomers have found evidence of the formation of planets and iron-containing building materials in the inner region of a circumstellar disk… more

To identify planets with potentially life-friendly oceans, one could compare the carbon dioxide levels of their atmospheres with those of their neighboring planets, say astronomers… more

How could this heavyweight emerge? Astronomers have discovered a surprisingly massive planet in close orbit around a very small star… more

A turbulent gas envelope in sight: Astronomers have discovered signs of clouds of silicate particles in the atmosphere of a “bloated” exoplanet, in addition to the signatures of water vapor and sulfur dioxide. It appears that intensive material transport in the hot gas envelope is causing this sand to settle in the high-altitude… more
